In Week 16, Atlanta quarterback Matt Ryan threw for 192 of his 348 yards after the 49ers took a 10-point lead with 12 minutes left.

On Sunday, Arizona's Carson Palmer threw for 292 of his 407 yards after the Cardinals trailed the 49ers 17-7 points at halftime.

On Wednesday, Green Bay's Aaron Rodgers pointed to those come-from-behind efforts when it was suggested that some late-season holes had developed in San Francisco's secondary.

"They were ahead pretty good in both games," Rodgers said. "So that's what they can do to an offense: ... force you to be one-dimensional. When you're behind, you've got to throw it a bunch. You're going to give up some yards. I don't think (the 49ers are) too concerned about that."

The 49ers, of course, hope Rodgers' nothing-to-see-here assessment is correct as they prepare to face the 2011 NFL MVP in a wild-card game Sunday at Lambeau Field.

In their final two games, the 49ers allowed 755 passing yards, their most in back-to-back regular-season games since they allowed 821 in September 2005. They also allowed 11 completions of at least 20 yards after surrendering 32 such pass plays in their first 14 games.

Now they probably will face Rodgers without starting cornerback Carlos Rogers, who injured his hamstring in the final minute of Sunday's win at Arizona and didn't practice Wednesday.

Meanwhile, the Packers' pass-happy offense is getting healthy. On Sunday, Rodgers returned after missing seven games with a broken left (non-throwing side) collarbone and threw for 318 yards and two touchdowns with two interceptions in a win-or-head-home 33-28 victory over the Bears. His game-winning 48-yard touchdown pass in the final minute went to wide receiver Randall Cobb, who had returned after missing 10 games with a broken leg.

Rodgers, who threw for 333 yards and three touchdowns in a 34-28 season-opening loss to the 49ers, said he felt fine after some rust was removed Sunday.

"It's a little bit like preseason after taking such a long layoff," he said. "Kind of want to get that first hit out of the way, that first completion and get the adrenaline flowing. It's one thing to practice for a few weeks, but it's another to be back out there in the live game reps. I felt good."

Niners safety Donte Whitner said he still feels good about the secondary, which was mostly stellar this season. The 49ers ranked seventh-best in passing yards allowed (221.0 per game) and fifth in touchdown passes surrendered (19), and quarterbacks had a 76.4 passer rating against them, the fourth-lowest figure in the NFL.

Whitner said the final two games were "no concern," but later acknowledged one area has to be addressed against Rodgers, who had six completions of at least 22 yards Sunday. Against Arizona, the 49ers allowed eight completions of 23 or more yards, including plays of 49 and 44 yards.

"We can't give up the big plays," Whitner said. "We've been (avoiding) that all year, but the last two weeks, we have been giving them up. In practice, we're going to correct that. Fix that. We're not going to give up the big play. We're going to make them earn everything that they get, and that's how you have a good secondary."

Said rookie safety Eric Reid, who was beaten for a 39-yard touchdown against Atlanta: "Obviously the focus of this game with such a pass-heavy team is to minimize the passing yards. Those guys are going to make plays; we've got to bend but not break."

The 49ers probably will attempt to do so with No. 4 cornerback Eric Wright playing a substantial number of snaps. If Rogers can't play, Wright will play nickelback, a spot that figures to see plenty of action.

Wright, 28, has played only 120 snaps in six games this season, but Whitner noted he's not an ordinary backup. Wright has made 81 career starts and played well enough to land a five-year, $37.5 million contract from Tampa Bay in 2012. He was released by the Buccaneers in July after a string of off-the-field issues.

"He's not like a bum off the street," Whitner said. "He was a guy that just scored a 30-plus-million dollar contract ... before he got into the off-the-field stuff, so he can actually play the game. ... He's a really, really good football player. So it's not like we're picking someone off the street and making them play."
